Arithmetic Mean and Geometric Mean
Arithmetic mean (AM) and geometric mean (GM) are two important types of mean in mathematics. In statistics, both are used to calculate the average of a given set of numbers. While the arithmetic mean is used to calculate the average of a group of numbers, the geometric mean is used to calculate the average of a set of proportions or ratios.
The arithmetic mean is the sum of all numbers in a set divided by the total number of items in the set. It is a measure of central tendency which is calculated by adding up the values of a set of numbers and then dividing the sum by the number of items in the set. This is also referred to as the arithmetic average. For example, if the set of numbers is 2, 4, 6, 8 and 10, the arithmetic mean is (2 + 4 + 6 + 8 + 10) / 5 = 6.
The geometric mean on the other hand is the average of a set of numbers or proportions obtained by taking the product of the numbers and then taking the nth root of the product, where n is the number of items in the set. It is a measure of central tendency which takes into account the relative magnitudes of the numbers in the set. For example, if the set of numbers is 2, 4, 6, 8 and 10, the geometric mean is (2 x 4 x 6 x 8 x 10)^(1/5) = 6.
Arithmetic mean and geometric mean are both used to calculate the average of a given set of numbers. However, it is important to note that the way of calculation differs and so does the result. Therefore, it is advisable to use the right type of mean depending on the context.
